Termo relay on arduino i need help

Try this code:

/*
  Connect thermistor between Vref and the reference resistor.
  Vref--Rt--Rref--GND, where Vref = 5V
  Rt = R0 * ((Vref/Vout)-1)
*/

const int Vout_pin = A0;	// ADC Pin to which the voltage divider is connected
const int num_samples = 5;// Number of samples for average                          
const int Rref = 10000;  	// Value of reference resistor used for the voltage divider
const int Max_ADC = 1023; // Maximum ADC value (for 10 bit = 1023)


void setup()
{
  Serial.begin(9600);
}

void loop()
{
  int i;
  float ADC_average;
  int samples = 0;
  float Rt;

  // Read the thermistor voltage num_samples times
  for (i = 0; i < num_samples; i++)
  {
    //samples += analogRead(Vout_pin);
    // for testing
    samples += 974;

    delay(10);
  }

  ADC_average = samples / num_samples; // Average voltage
  Serial.print("ADC readings ");
  Serial.println(ADC_average, 0);

  // Calculate thermistor resistance
  // Rt = R0 * ((Vref/Vout)-1)
  // If Vref is same volatge for the ADC then
  // Vref/Vout = Max_ADC/ADC_average

  Rt = Rref * ((Max_ADC / ADC_average) - 1.0);
  Serial.print("Thermistor resistance ");
  Serial.println(Rt, 1);

  // Calculate temperature
  float temperature;
  temperature = 273.1 - ((100.0/650.0) * Rt); 
  Serial.print("Temperature ");
  Serial.print(temperature, 1);
  Serial.println(" *C");
  Serial.println("\n");
  delay(1000);

}

If it does not work maybe someone else can help. I need to leave for now
